Beschreibung
Zusammenfassung:	The invention relates to a method of generating ultrasounds in a given fluid by using at least one micro-machined capacitive transducer (cMUT) (100) comprising a membrane (102) and exhibiting a predetermined resonant frequency defined by the membrane-fluid pair, characterized in that said at least one transducer (100) is fed with an excitation signal of lower frequency than said central frequency. It also relates to a device for generating ultrasounds implementing cMUTs as well as a method and system for medical imaging. L'invention concerne un procédé de génération d'ultrasons dans un fluide donné en utilisant au moins un transducteur capacitif micro-usiné (cMUT) (100) comprenant une membrane (102) et présentant une fréquence de résonance prédéterminée définie par le couple membrane- fluide, caractérisé en ce que ledit au moins un transducteur (100) est alimenté avec un signal d'excitation de fréquence inférieure à ladite fréquence centrale. Elle concerne également un dispositif de génération d'ultrasons mettant en oeuvre des cMUTs ainsi qu'un procédé et système d'imagerie médicale.
